Specification of Letters Patent.

Patented Mai. 28, 1916.

To all whom if may concern Be it known that I, ELISA M. SoUvIELLE, acitizen of the United States, residing at Jacksonville, in the 4countyof Duval and State of Florida, have invented certain new and usefulImprovements in Transmission- Gears, of which the following is adescription.

My invention belongs to that general class of devices employed for thetransmission of power by' means of gears, sprocket Wheels, belts, ropes,chains, lor the like, and relates particularly to an element arranged tobe used in connection with any of the means referred to.

VThe invention has among its objects the production of a light weighttransmission member that is of great strength, and one in which theparts may be quickly and economically renewed in case of breakagewithout removing or discarding the entire structure.

It also has among its objects the production of a device of the kinddescribed that is simple, convenient, durable, efcient, andsatisfactory, that maybe manufactured at comparatively low cost andusedwherever found applicable.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawings, wherein like reference characters 4indicate like orcorresponding parts, Figure 1 is a plan view of one form of my device;Fig. 2 is substantially a sectional view taken on line 2, 2 of Fig. 1;Fig. 3 is a sectional view of aslightly modified form; Fig. 4 is a planview of another slightly modified form; Fig. 5 is substantially asectional view of the same taken on line 5, 5 of Fig. 4, and Fig. 6 is adetailed view of a modified construction.

Referring to the form of device shown in Figs. 1 and 2, 1 represents asuitable shaft, which may be the driving or driven shaft, as the casemay be. Arranged on this shaft is a plate or plates, or disk 2, whichmay be cut away as at 3. 3, etc., to reduce the weight. As shown, theplate 2 is of comparatively light weight, and is reinforced orstiened bybolts 5 secured thereto and to a plate 4 arranged on the shaft. Thebolts 5 may be bent as shown, or the plates may be formed so thatstraight bolts may be employed, or washers of suitable shape arranged atthe ends of the bolts where they are straight to afford bearings for theheads and nuts of the bolts. Carried by the plate 2 are a plurality ofdetachable members 7 arranged forI coperation with a sprocket wheel,gear wheel, belt, rope, chain, or the like, these either being driven bymy device or arranged to drive it. I also preferably employ an auxiliarymember in the form of a ring or plate 6, which is arranged onthe end sof the members 7 and braces them. '.ljhis may be secured in place in anydesired manner, nuts being shown for the purpose.

Sleeves or tubes 8 are preferably placed 0n the bolts, the same servingto space the ring 6 from the plate 2, as well as to reduce the frictionbetween the device andthe coperatin driving or driven parts. Any desirednum er of bolts may be employed, and they may be arranged as desired. Inthe. form .shown in Figs. 1 and 2, they are so arranged that the tubesor members 8 extend slightly beyond the periphery of the plate or disk 2and ring 6.

In the construction shown in Fig. 4, and the sectional half of Fig. 5,15 is a plate or disk arranged on ashaft 14, the samebeing suitablyconnected and braced by a plate 16 and bolts 17, or their equivalentsfor the purpose. Arranged on one side of the disk 15, as shown, on theside opposite the plate 16, is a plate 18, this being in the form of 'aring of less diameter than the plate 15. Plate 15 and ring 18may beflanged as at 21 and 22, the two parts being connected by members 19, inthe construction shown bolts being employed, upon which may be arrangedtubes or sleeves 20. This construction is very similar to the one shownin Figs. 1 and 2, except that the pins or detachable elements are atanangle to the shaft 14, similar to a bevel gear.

Another form is shown in Fig. 3, in which '25 is a plate arranged onshaft 26, the same being braced and stii'fened by the plate 27 and bolts28, or their equivalents for the purpose. As shown, plate or disk 25 isflanged about its periphery, as at 29, and bolts or the equivalent 31extended therefrom, either internally or externally, as shownexternally. A ring 30 or its equivalent is arranged about the largerends of the bolts 31, and tubes or sleeves 32 arranged on the bolts.Ihese operate asin the other construction, and likewise serve to spaceand maintain the ring in position. It is, of course, obvious that theflange 29 may be turned as shown or toward the opposite side of thedevice, with this construction, and the same is also true of the otherconstruction. The same may then drive or be driven from either side, orfrom both` sides, or at a plurality of points, from either or bothsides, as will be obvious from the preceding description.

Great variation is possible in the construction of the device, the broadfeature being that the device may be employed for the transmission ofpower in cooperation with a belt, rope, cham, sprocket wheel, or thelike coperating or acting with a series of movable elements or units,which device can be quickly and easily repaired or reconstructed withoutremoving or discarding the entire device. In the preferred embodiment ofthe device-two or more plates or disks of metal of equal or differentsize according to the required service, are employed, which areconnected at any desired angles by bolts,

or the equivalent, and spaced by sleeve members. The device differs fromall others in that it does away with what has been previously consideredessential weight. As it is not a circle, 'but rather a polygon whencooperating with belts, chains, or other means of transmission, all slipis prevented, as the slight angle of the members grasps and pushes therope, chain, or the like, or is ushed thereby. In other words, it doesno? depend entirely upon friction; consequently runnin expense isdecreased or eiliciency increase The plate at the side of the device towhich the bolts are attached balances the periphery and stabilizes thewhole wheel, the same affording leverage for minimum weight. Inasmuch asit can be placed upon either side, either side of the plate may be clearfor the application of power. Where a greater number is required, or thewheels are the same size, a plurality I of plates may be used where .oneis shown 1n the drawings. There being no dead weight there is no dangerof explosion, and the device will develop greater pow'er at theperiphery and .transmit more with the same l propelling power requiredon a heavier device, the teeth, if the tubes or rollers may be sotermed,vv being capable of rotatlon, to a large extent tend to decreasefriction, particularly where the device is used with a toothed drivingor driven member.

In Fig. 6, the plates 35 and 36 carry bear- 'ing members 39, 40, 41 and42, beveled to afford bearing faces for the sleeve 38 and bolt ends, 37being the bolt. These members may be formed on the plates or separabletherefrom.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same within the scope of theappended claims without departin from the spirit of my invention; henceIdo notwish to be understood as limiting myself to the exact form,construction, arrangement and combination of parts herein shown anddescribed, or uses mentioned.
